Crowns and Bridges
Crowns and Bridges are examples of restorations in dentistry. Crowning means to protect a damaged tooth and making a bridge means to replace a missing tooth or teeth. The aim is to give you a natural smile, prevent plaque and improve your oral health. A missing tooth can affect your appearance, your health and your confidence about yourself. There are three different ways to replace a missing tooth or teeth: 1- Crowns and Bridges 2- Dentures 3- Implants.
A crown is a tooth-shaped cap which will be fitted with a special glue or ‘cement’ over a tooth. They strengthen and protect the tooth.
There are different crowns with different materials as below:
- Bonded Porcelain Crowns: These crowns are made from a precious metal base and then porcelain is applied in layers over them.
- All Porcelain Crowns: They are made entirely out of porcelain.
- Gold Alloy Crowns: Gold will be used with other metal alloys to increase its strength. The colour can be gold or silver.
Procedure for crowning:
1- Consultation: Full examination of proposed tooth or teeth, X-ray(s) and explaining the process and also the cost.
2- Preparation: The shade (colour) of the crown(s) which best matches your own teeth is chosen. Local Anaesthetic will be applied, preparation (removing) of enamel layer (1-2 mm), Impression (Mould), then temporary crown(s) will be applied. It normally takes two weeks to receive your crown(s).
3- Fitting: Temporary crown(s) will be removed. The dentist will check the need of Local Anaesthetic. The crown(s) will be shown to you on the model and also on the tooth or teeth. The dentist will check your bite pattern or ‘occlusion’ and contact points with the next teeth. You can check the crown(s) and the shade in the mirror. Then the dentist will fit the crown(s) with a special cement and check the crown(s) and your occlusion again.
Bridges fill the gap for a missing tooth or teeth. It prevents the next teeth leaning into the gap and changing your bite. A gap can affect your bite, cause decay and gum problems. The procedure is almost the same as for crowns - consultation, preparation and then fitting are still required. Instead of individual crowns, it will be 2,3,4 etc. crowns attached to each other as a single unit. Therefore it will be named as ‘2 unit bridge’, ‘3 unit bridge’ etc. The material can be Porcelain bonded to precious metal, which is what most bridges are made of.
